added $InputTCPServerAddtlFrameDelimiter config directive, which
enables to specify an additional, non-standard message delimiter
for processing plain tcp syslog. This is primarily a fix for the invalid
framing used in Juniper’s NetScreen products. Credit to forum user
Arv for suggesting this solution.

added $InputTCPServerInputName property, which enables a name to be
specified that will be available during message processing in the
inputname property. This is considered useful for logic that treats
messages differently depending on which input received them.

added $PreserveFQDN config file directive
Enables to use FQDNs in sender names where the legacy default
would have stripped the domain part.

bugfix: imudp went into an endless loop under some circumstances
(but could also leave it under some other circumstances…)
Thanks to David Lang and speedfox for reporting this issue.
